Uniswap V3 LP Performance HUD

A quick way to monitor the performance of your Uniswap V3 positions. Displays current APR, daily estimated yield and annual estimated yield.

Features

Generates the HUD.
Automatically checks the chain for deposit transaction timestamp, to calculate APR.
- Warning: CORS issues on occasion, falls back to manual timestamp entry.
- Saves deposit time to local storage.
- HUD updates when Uniswap "Unclaimed fees" updates, which is useful when a position is young.

Installation

For Users

Create a new bookmark in your browser.
You can name it anything you want.
In the URL field, paste the below code.
Save and press the bookmark when you're viewing your position.

javascript: (() => {
	const script = document.createElement("script");
	script.setAttribute("src", "https://github.com/pavlovcik/uniswap-lp-apr/releases/download/latest/index.js");
	document.body.appendChild(script);
})();

That's it!

For Developers

yarn && yarn build

This will export an optimized version to dist/closured.js using google-closure-compiler

Bookmarklet

Create a bookmarklet with the following "URL" to quickly prototype changes when using yarn watch to build automatically on change.

javascript: (function () {
	const script = document.createElement("script");
	script.setAttribute("src", "http://localhost:8888/index.js");
	document.body.appendChild(script);
})();

This will expose closured.js on localhost for fast prototyping in the browser using yarn serve. Just click the bookmarklet to reload!

Troubleshooting

Google Closure Compiler

Randomly, on my M1 Mac I started getting Error: spawn Unknown system error -86 when trying to launch Google Closure Compiler.

Turns out the solution was to install rosetta? Even though I'm pretty sure I already had it, given that I was building this project a couple days ago on the same machine.

softwareupdate --install-rosetta
